I don't think so, they only offer bigger profit in situation if price will go to the moon cause other aspects make price going up so i can't agree with that statement.
Of course that coins with a lower market cap offer better possibilities that they moon, look at bitcoin do you think it is going to the moon soon, it is the best coin we have but its price is very high already, but a coin with only a few million in the market cap only needs to reach a few hundred million in the market cap to give you incredible profits.
